Provincial regulations prohibit pruning elm trees from April 1 to August 31 during the time when elm bark beetles are most active. Regulations also prohibit the storing, transport and use of elm wood. The only permitted movement of elm wood is to the City of Saskatoon Landfill which is the designated disposal site in Saskatoon. Report symptomatic trees to 306-975-2890. See www.saskatoon.ca/services-residents/housing-property/city-owned-trees-boulevards/tree-diseases-pests.
